    Abstract: A primary alkaline cell having a stable divalent silver oxide depolarizer mix comprising a negative electrode (anode), a divalent silver oxide (AgO) depolarizer mix, a separator between said negative electrode and depolarizer mix, and an alkaline electrolyte. The surface of the depolarizer mix is treated with a mild reducing solution to form a reduced layer surrounding the mix, and the surface of the reduced layer adjacent to the separator is coated with a layer of silver. The reduced layer surrounding the depolarizer mix in combination with the layer of silver provides improved stability of the depolarizer mix in the alkaline electrolyte and a single voltage plateau during discharge of the cell. The primary alkaline cell is characterized by a maximum open circuit voltage of about 1.75 volts.

    Abstract: A method for manufacturing a stable divalent silver oxide depolariser mix wherein the mix is treated with a mild reducing solution of a reducing agent such as methanol followed by a treatment with a strong reducing solution of a reducing agent such as hydrazine to form a layer of silver on the surface of the depolarizer mix. The depolarizer mix is specially prepared for use in a primary alkaline cell which is discharged at a single voltage plateau, and the preliminary treatment of the mix with the mild reducing solution permits the incorporation of greater amounts of divalent silver oxide in the mix, thereby increasing the electrochemical capacity while still providing a single voltage plateau discharge. The treatment with the mild reducing solution generally requires soaking the mix in a solution containing a reducing agent for up to 10 minutes and may be carried out at either room or elevated temperature. The subsequent treatment with a strong reducing solution may also require up to about 10 minutes at either room or elevated temperature, with the purpose to provide a substantially continuous and electrolyte permeable layer of silver on the surface of the depolarizer mix. The depolarizer mix is particularly adapted for use in a "button" cell construction, and it may contain from about ? by weight to about 100% by weight of divalent silver oxide and still provide a cell with a single voltage plateau discharge.
